STORING AND RECLAIMING- APPARATUS.

Application filed December 22, 1917.

T 0 all whom it may concern:

Be it known that I, FRANCIS LEE STUART, a citizen of the United States, and a resident of the city of WVashington, District of Columbia, have invented certain new and useful Improvements in Storing and Reclaiming Apparatus, of which the following is a specification.

This invention relates broadly to a storing and reclaiming apparatus, and more particularly to an apparatus of this type for receiving materials from a main source of supply, conveying the same to storage, and then reclaiming and reloading the same.

The principal object of the present invention is to provide an apparatus constructed of a plurality of units which may be readily brought into position and assembled for use.

A further object of the present invention is to provide each unit conveyer with means for driving the same, and also with means for moving the unit from place to place for use as desired.

A further object of the present invention is to provide a transfer table adapted to receive the material to be handled from a main conveying means, and cooperating with the unit conveyers whereby the material may be readily transferred thereto.

Still another object of the present invention is to provide a stacker or trimmer which is complete and portable from place to place to cooperate with any desired source of supply.

A still further object of the present invention is to provide a system employing the various apparatuses before referred to whereby material may be quickly and easily received from a main source of supply, such as a track hopper, and conveyed tostorage devices from which it may be reclaimed and reloaded at will.

The foregoing and other objects, together with their attendant advantages, will be apparent from the accompanying specification, and drawings forming a part thereof, throughout the several views of which like characters of reference have been used to indicate like parts. In the drawings, which are largely diagrammatic, Figure 1 is a perspective view of my improved apparatus showing the same in position for receiving material from a track hopper, and deliver- Specification of Letters Patent.

In handling material in bulk, such as coal, ore, and the like, it is necessary in order to expedite the loading of the same that both a main and secondary source of supply be provided. In systemswith two sources of supply, it is customary to replenish the secondary source of supply from the main source, and then subsequently reclaim and reload from the secondary source. Belt conveyers, commonly employed for this purpose, frequently have a length of several hundred feet, so that the cost of installation and upkeep is an item of considerable importance. Furthermore, where continu ous belt conveyers are employed it is necessary to provide troughing and supporting rollers for the upper and lower run of the belt, respectively, so that the entire conveyer when once installed is more or less fixed. It is the object of this present invention to provide sectional or unit conveyers which Patented Aug. 13, 1918.

of a track hopper may be kept on hand-in any desire d number the receiving hopper 5 feeding the main conveying means, here shown as a belt con- I veyer 6. The track hoppers and associated mechanism may be. placed, as is customary justable with the tripper.

in this art, in pits 7 whereby the cars C are Q easily moved to discharging position over the same; v For storing the material received from the track hoppers, the main conveyer 6 has a looped portion 8 passing around the trippen-'9 adjustable on the track 10 by means of a motor or the like 11. The tripper may be of the type disclosed in my Patent No.

1,207 ,237, of December 5, 1916. The frame work of the tripper is connected at '12 to a transfer table T on' the tracks 10 and ad-v If desired, the transfer tablemay also be provided with a source of power 14 so that the same may be independently moved to the desired position. The upper end of the tripper 9 discharges into a hopper 15 having oppositely extending outlets 16 for delivering material to the shuttle conveyer 17 mounted in the frame 18, and having suitable driving mechanism 19. The shuttle conveyer is adjustable on the frame 20 of the transfer table by means of the motor 21, and is providedwith discharges 22 adapted to be brought into operation in accordance with the direction of travel of the shuttle conveyer. The discharges 22 are disposed in cooperative relation to the upper run of the unit conveyer belts 24 mounted on the frames 25 which are self-movable by the driving mechanism 26.- An operating means 27 for the unit conveyers makes the same self-contained so that each unit may be used independently of any other unit, or may be used in conjunction therewith. The unit conveyers preferably have their ends 28 inclined and provided with hoppers 29 whereby an independent unit conveyer may be moved to cooperating position therewith. The entire transfer table T is preferably disposed in a pit 30 so that the upper surface of the transfer table is flush with the surface of the adjoining ground. By reason of this construction the unit conveyers 24 may be readily moved onto the transfer table and projected therefrom so as to receive material from the discharges 22. The transfer table may be constructed so that any number of unit conveyers may be simultaneously. carried thereon. The unit conveyers as they receive material from the shuttle conveyer 17 discharge the same onto the tripper 31, constructed in a manner similarto the tripper 9 and discharging to the stacker S forming storage piles, or secondary sources of supply I.

From-the foregoing description, it will be obvious that by reason of the unit conveyer construction, the 'positionof the stacker S may be controlled at will so as to deposit material adjacent the main conveyer 6 when only a single unit is employed, or at a considerable distance therefrom when a plural ity of units are utilized. As clearly shown in Figs. 1 and 2 the unit conveyers 24 may be positioned and kept on sidings 32 from which they may be easily run onto the transfer table T and moved to a position in which they will cooperate with the main conveyer.

By employing a shuttle conveyer, the material supplied by themain conveyer may be delivered to a unit conveyer not located on the transfer table as indicated inFig. 4 even though the transfer table carries a spare 16, although in actual practice the con-v veyers in assembled relation occupy such positions that comparatively little space exists therebetween. v

In still other cases it is desirable to employ a stacker S, fully illustrated in Figs.

10 and 11, which is self-contained and movable as a unit from place to place. This stacker comprises a framework 34 traveling on the wheels 35 and carrying a conveyer belt 36 driven by the motor 37 The main difference between this construction, and that disclosed in Fig. 6 resides in the employment of a conveyer 36 which is independent of any other conveyer belt, but

which is adapted to cooperate therewith for receiving materials. For example, a unit conveyer 24 may supply material thereto through the hopper 29 positioned adjacent the lower end of the frame 34. At its upper end, the conveyer 36 discharges through a hopper 38 and out1et39 to the stacker S pivotallysupported on the trunnions 40 carried b the rotatable or turntable construction 4i carried by the truck 42. The truck 42, as is the case with the other trucksem- I ployed throughout my apparatus is preferably driven by a motor 44 so that the stacker may be moved to storing position. Angular adjustment of the stacLer is obtained by the motor 45 driving the pinion 46 cooperating with a segmental rack gear 47. Due to the turntable support for the stacker it is easily swung or adjusted laterally, as indicated in dotted lines in Fig. 10. The self-contained construction rendering the entire stacker and tripper easily portable is highly advantageous in that the necessity of employing a separate tripper and stacker for each belt is overcome.

After the material has been stored in piles or warehouses P, it may be readily reclaimed by employing a reclaimer R, which may be constructed in accordance with any of the forms disclosed in my copending application, Serial No. 201,798 filed Nov. 13, 1917. As herein shown, the reclaimer comprises a reclaiming digger 48 elevating material to the boom conveyer 49 having one end supported in coiiperative relation with the hopper 50 mounted on the adjustable truck 51. The truck 51 is preferably mounted to discharge-to a unit conveyer'24 of the type described delivering through the connecting hopper 29 to a stacker or loading trimmer S adapted to deliver either to the cars C or to the conveyer 52, which may in turn load either the barges B or the vessel V through the trimmer 54, which may be constructed as disclosed either in my Patent No. 1,207,237, of December 5, 1916, or No. 1,231,449, of-

June 26, 1917. In Fig. 7, the discharging end of the reclaiming conveyer is shown in detail, together with the motor 55 for driving the same, and the motor 56 for producing longitudinal adjustment of the truck 51 through the driving belt 57 and its associated mechanism.

In some cases I may employ a modified mounting for the reclaimer 49. Such a modification is illustrated in Fig. 6 in which the truck 51 is illustrated as being carried by the transfer t-ableoT in cotiperative relation with one of the unit conveyers 24. Such a construction permits'the rapid positioning of a unit conveyer by reason of the pit construction 30.

In like manner, the stacker S may be mounted on the transfer table, as shown diagrammatically in Fig. 9.

By employing self-contained unit conveyers, and self-contained trimmers and stackers which may be easily moved from one point to another, an expeditious and economical handling of material is effected. Any means may be employed, if desired, for interconnecting the unit conveyers,although such a construction is not necessary, by reason of the fact that each conveyer may be independently moved to its final position.
